What It Is: A skin-perfecting, anti-dullness, and radiance-boosting make-up primer. What It Does: Meteorites Primer smooths and color-corrects your skin tone for a radiant complexion. Infused with a delicate violet scent. Formulated with Guerlain's signature Stardust Technology: a unique complex encapsulating a celestial powder that transforms light invisible to the naked eye into visible and soft-focus perfecting light to blur imperfections and provide exceptional radiance. The fresh gel texture melts with the rosy pearls to give skin a radiant and glowing finish. Highly concentrated pearls containing multi-colored, micro-shimmer particles amplify light reflection to create an illuminating, color-corrective light for your complexion. The absorbent powders neutralize excess oil while a special polymer helps to fade imperfections and smooth fine lines for a long-lasting, matte and even complexion. How to Use: The first step in your make-up routine and should be applied in the morning after your usual skincare, alone or as a base for makeup. For an optimized application take a small amount of the product and warm it between your fingers to melt the pearls.
